As shown in Figure 18-26, a kind of air-conditioning air inlet/outlet structure, the air inlet/outlet structure includes air inlet structure and outlet air knot Structure, the air exhausting structure include the air-out passage formed by the lower case 3 and vane 5 out.

On the air-inlet grille 1, the outer diameter of the air-inlet grille 1 is denoted as R1；One is done on the air-inlet grille 1 Circle, the circle are so that the smallest circle of radius that all air inlet holes 101 on the air-inlet grille 1 are all located in the circle, by institute It states round radius and is denoted as R3.

On the vane 5 out, the outer diameter of the vane 5 out is denoted as R4；The radius of the air outlet 502 is denoted as R2。

Applicant passes through the study found that in the case where other structures, size and constant operating parameter, R1, R2, R3 and R4 Between relationship there is apparent influence on air output and intake.

Firstly, the relative size of research discovery R3 and R1 has large effect to intake: specifically, if R1 is fixed not Become, during air inlet, with the increase of R3, the intake of the air-inlet grille 1 is also gradually increased, but when R3 is increased to centainly After degree, the intake of the air-inlet grille 1 no longer increases with the increase of R3, to find out its cause, be because with from it is described go out The air-flow blown out in air port 502, which produces, to influence each other.Therefore, the application is to the relative size of R3 and R1 to air inlet index W Influence is studied.Wherein, air inlet index W be the air-inlet grille 1 current intake with when R3 be equal to 0.5R1 when described in into The ratio of the intake of style grid 1.In general, air inlet index W is bigger, indicate that the intake of air-conditioning is also bigger, correspondingly, air output Also it can increase with it, the energy consumption of air-conditioning will reduce.When entering the wind index W greater than 2.5, identical refrigerating capacity, the air-conditioning are realized The energy consumption of air inlet/outlet structure can reach effective energy-efficient effect lower than entering the wind 70% of energy consumption when index W is 1.

As shown in figure 26, the present embodiment each assembling structure between the other structures and size and air conditioner of air-conditioning Under the premise of size and assembly relation are constant, the relationship between air inlet index W and R3 and R1 is studied, specific data are such as Following table:

R1(cm)	R3(cm)	R3/R1	Enter the wind index W
				40	20	0.5	1
40	22	0.55	1.61
				40	24	0.6	2.12
40	26	0.65	2.51
				40	28	0.7	2.79
40	30	0.75	2.96
				40	32	0.8	3.02
40	34	0.85	2.97
				40	36	0.9	2.81
40	38	0.95	2.53
				40	39	0.975	2.36

The relationship obtained between the air inlet index W and R3 and R1 meets formula:

W=-22.2 (R3/R1)²+ 35.6* (R3/R1) -11.25, wherein R1 and R3 is positive number, and R1 > R3.

When the ratio R 3/R1 between R3 and R1 is between 0.65~0.95, the air inlet index W is greater than 2.5, so, The present embodiment chooses the ratio R 3/R1 between R3 and R1 and is used as optimum ratio range between 0.65~0.95.

Further, research finds that the relative size relationship of R2 and R3 has large effect to air output: in general, if protecting It holds R1 and R3 is constant, with the increase of R2, be beneficial to the air that air-conditioning blows out the air outlet 502 and be discharged.Generally, institute State between the air and room air blown out at air outlet 502 the air that there are pressure difference, is blown out from the air outlet 502 according to It flows out from the air outlet 502 by the impetus of blower and the effect of the pressure difference, and after being mixed with room air, reaches To the purpose for adjusting indoor air temperature.There is complicated air movements during this, firstly, with the increase of R2, it will It is discharged conducive to air-conditioning inner air via the air outlet 502；Secondly, with the increase of R2, air at the air outlet 502 The active force of pressure and the blower being subject to will reduce, and the move distance of the air blown out from the air outlet 502 indoors will It reduces, is unfavorable for being sufficiently mixed for blow out air and room air at the air outlet 502；Furthermore air from annular outlet air When mouth 502 is blown out, the air that can produce similar bladeless fan doubles effect, so that being located at the sky of 502 inner side and outer side of air outlet Gas is under the drive of the air blown out out of air outlet 502, and the air blown out in retinue's air outlet 502 moves together, accelerating chamber Interior air flowing, promotes the effect that air-conditioning adjusts room temperature.Further, these annulars to the air-flow blown out outside air-conditioning It further interacts with air inlet air-flow at its center, produces more complicated air movement phenomenon.A series of this sky Gas motion process influences each other, so that the relative size relationship of R2 and R3 generates large effect to air output.Therefore, this Shen Please the influence to the relative size relationship of R2 and R3 to outlet air indices P is studied.Wherein, outlet air indices P is current air output With as R3/R1=R1/R2=0.8, the ratio of the air output of the air outlet 502.In general, outlet air indices P is bigger, indicate empty The air output of tune is bigger, and the room temperature regulating effect of air-conditioning is better, and energy consumption is lower.When outlet air indices P is greater than 1, can reach Effective energy-efficient effect.

As shown in figure 26, the present embodiment each assembling structure between the other structures and size and air conditioner of air-conditioning Under the premise of size and assembly relation are constant, the relationship between outlet air indices P and R3 and R2 is studied, specific data are such as Following table:

R1(cm)	R2(cm)	R3(cm)	R3/R2	Outlet air indices P
					40	41	32	0.78	0.98
40	42	32	0.76	1.04
					40	43	32	0.74	1.07
40	44	32	0.73	1.09
					40	45	32	0.71	1.10
40	47	32	0.68	1.09
					40	50	32	0.64	1.00
40	53	32	0.60	0.89
					40	62	32	0.52	0.38
40	65	32	0.49	0.18

The relationship obtained between the outlet air indices P and R3 and R2 meets formula:

P=-20.45 (R3/R2)²+ 28.82* (R3/R2) -9.05, wherein R2 and R3 is positive number, and R2 > R3.

When the ratio R 3/R2 between R3 and R2 is between 0.64~0.76, the outlet air indices P be more than or equal to 1, therefore This, the present embodiment chooses the ratio R 3/R2 between R3 and R2 and is used as optimum ratio range between 0.64~0.76.

Further, research finds that the value of R4 also has certain influence to outlet air indices P, when the difference between R4 and R2 Value, i.e. when 5cm < R4-R2 < 25cm, the air output of air-conditioning is larger.
